When Operation rlan 3-586 for the TEAK and OkAnG& events was pub
lished on 25 June 1958, the general concept of the NewSiehh operation

and of Task Group 7.4 responsibilities became much more crystallized.
Several prominent changes were now noticeable,
For example, a C-97 and two AV2 aircraft which had not been listed

in the original inventory of test aircraft by Task Group 7.4, had now
been included for NawSKasL participation.

These ai.craft, however, had

been listed in the Joint Task Force SxVuN Operation Crder 35=58 on 13

June 1958.

‘The B+36 aircraft were to engage in (1) a project to ascer

tain eye effects resuiting from high altitude, high yield detonations, ~

(2) a project to measure and analyze the thermal phenomena resulting
from the detonation of nuclear weapons at very high altitudes, (3) a
project to determine the modes by which energy is propagated and dis~
sipated from nuclear explosions at high altitudes and to document all
visible aspects of the detonation, and (4) a project to photograph at
4J,000 feet the spectrums of both shots as a function of time Juring
early fireball growth.
The P2V aircraft was to take part in a project dealing with air
borne infra-red measurements, the aircraft flying at 25,000 feet.
one C-97, sponsored by the sir Force Meaical Center, was to engage
in a project with the two B-36's, that of ascertaining eye effects re-

sulting from hi,n aititude, nigh yield aetonations,
